ARRACACIA DoNNELLSMITHII C. & R.—Volcan de Agua, 
Dept. Zacatepequez, at an altitude of 10,000 ft. Collected 
near the type locality by W. C. Shannon, June, 1892. 
Arraeaeia Luxeama, n. sp.— Probably a tall perennial, 
branching, glabrous: leaves ternate to triternate; petioles 
wholly inflated; leaflets ovate to lanceolate, 2.5 to 7.5" 
long, sharply serrate, glabrous: peduncles short (10 to 127 
long) or wanting: umbel somewhat unequally 15 to 30-rayed, 
with involucre wanting or of a single leaflet; involucels four 
to eight, foliaceous, lanceolate, sharply serrate, often 2.5" 
long; rays 5 to 10" long; pedicels 8 to 14^" long: fruit ovate, 
acute, 6 to 8"" long, glabrous, flattened laterally, with slender 
conical stylopodium: carpel terete, with five prominent ribs; 
commissure narrow; oil tubes solitary in the intervals, two on 
the commissural side: seed with deeply sulcate face and fur- 
rowed under the intervals.—In the forest near San Miguel 
Uspantán, Dept. Quiché, at an altitude of 6,000 to 12,000", 
April, 1892, no. 3,354. Collected by Lux. 
EULOPHUS PEUCEDANOIDES Benth. & Hook.— Santa Rosa, 
Dept. Santa Rosa, at an altitude of 3,000 to 4,000", May, 
1892, no. 3,353. Collected by Heyde & Lux. 
ENANTIOPHYLLA. n. gen.—Calyx-teeth obsolete. Fruit 
oblanceolate, flattened dorsally, glabrous.  Carpel strongly 
flattened dorsally: dorsal and intermediate ribs prominent, 
acute; lateral ribs winged. ^ Stylopodium slender, conical; 
styles furrowed on ventral face, slightly thickened above but 
not capitate. Oil-tubes solitary in the intervals, two on the 
commissural face. Seed sag flattened dorsally, with a 
broad, shallow excavate face an furrowed under the inter- 
vals. — Tall glabrous perennials, with opposite ternately-com- 
pound leaves, lanceolate acute leaflets, linear bracts and 
bractlets, and white (?) flowers. 
This genus belongs to Bentham and Hooker's subtribe 
ANGELICEX. From Azgelica and Prienosciadium it differs 
chiefly in its conical stylopodium and opposite leaves. In 
fact, in the latter character it differs from most genera of 
Umbellifere, and has suggested the generic name. The 
genus is peculiar in having the carpel developed at the base 
into a broad stipe or foot, much as in Dr. Robinson's new 
genus Cou/terophytum, but not so marked. It has several 
other characters in common with the latter genus, but has a.
